1:00 AM ET: Jimmy Kimmel opened his live show tonight as Leno and performed a full monologue in the former (and future?) Tonight Show host's style. Complete with a grey wig and prosthetic chin?even a makeshift Kevin Eubanks in band leader Cleto Escobedo?Kimmel decimated Leno with every passing second. Here's a few minutes of the hilarious?and hilariously biting?monologue.

1:45 AM ET: Later in the show, Kimmel did a mock Headlines segment (still as Leno) and then held an interview with Chevy Chase, who came out as Conan O'Brien, orange wig and all.

Don't you just love the late night wars? I can't wait for another HBO dramatisation in the vein of The Late Shift.
